For 56 points more than that E5N4A3 Gorgon you can get a E9N4 Gorgon who has great resistance to ranged weapons(18 prot unequipped) and can fight well unbuffed. She also makes a nasty bladewind caster and gives your centaurs a good survivability bless but she lacks the ability to broaden your magic access with air magic.

Just another option.

For a completely different pretender and bless an imprisoned, dom6 W9N9 lady of love can be fun as your sacreds get berserk +5, 21(17 without shield) defence not berserking, a respectable 16(12) defence berserking, 15 attack when berserking averaging 3 attacks per round(50% chance to act twice), regen, 14 prot berserking, 18 strength berserking and amazing speed(above 30, possibly in the low 40's) due to the W9 bless. You can also make some Hierophant thugs with that bless(personally i like gloves of the gladiator, horned helm and blacksteel full plate with that bless-the chance of a centaur with fairly minor equipment getting on average 9 strength 19(after berserk, before weapon strength is added) attacks and being able to reach rear troops/archers at the start of the battle is fun.
